Preview major or minor versions are released every 2 months. These versions contain new features and capabilities that might not be complete yet, but still offer value to the users.

Long-term support (LTS) versions are released roughly two times a year. These versions contain all completed features that were introduced in preview releases since the previous LTS version.

Note

Patch versions may be released as often as every week for all currently maintained/supported LTS versions of OroCRM Enterprise Edition.

The key difference between preview and LTS versions is the duration of the maintenance (bugfix) period. LTS versions are also supported for security fixes.

Preview versions are not maintained, unless announced otherwise.

LTS versions of OroCRM Enterprise Edition are maintained for 18 months after the release, and security fixes are released for 18 more months.

Below is the approximate schedule of the currently maintained/supported and planned upcoming releases and support timelines of OroCRM Enterprise Edition until 2020. Please take into account that numbering of major and minor versions is subject to change.

(Recommended) Long Term Stability – Upgrade from an LTS version to the next LTS version to take your time to adopt new features. Choose this model to receive continued support without necessity to upgrade frequently.

Bleeding Edge – Immediately utilize and benefit from new features as soon as they are introduced by always upgrading to the newest preview version every 2 months. Choose this model if you are an enterprise partner or an extension developer and you want to ensure that your extensions and customizations are tested in combination with all new features before the next LTS release.

If you are planning to start a new project this year which is scheduled to go live after January 2019, we recommend to start the development on the most recent release in 4.x series. You might need to continually upgrade to the next available 4.0, 4.1 versions (Beta, RC) and ultimately upgrade to 4.1 LTS version prior to going live with the project.

Oro Team produces patch releases for an LTS version of OroCRM Community Edition only until the next LTS version is released.

Community developers and users have access to the following two product branches:

Stable – 2.6 branch points to the latest LTS version. Use this branch for testing and deployment. To benefit from the latest features, fixes, and security updates, upgrade to the next patch release tag or LTS release tag as soon as they are available.

Development – 3.1 branch points to the latest available commit and is updated daily. This branch should be used only by the developers and contributors who actively follow the project progress on GitHub. This branch is not considered stable and it is not recommended for production use.
